This is a very simplistic implementation of a function that would be very useful if fully implemented. Unfortunately it doesn't take into account the myriad of language-specific exceptions to title case. In English, typically you don't "upper case" the first letter of words like "of" and "and". You don't lower case the 2nd/3rd letters of some Celtic surnames (eg. McCall or O'Toole). Sometimes you don't lowercase the first letter after a hyphen (eg. Guinea-Bissau). I'm sure there's more, it's a bit mind-blowing when you get into it!
